A plane leaves Charlottetown, PEI at 12:00pm on Saturday, May 2nd. The destination is Yellowknife, NWT. The flight takes 17 hours. What is the date and time of your arrival in Yellowknife?

5am on Sunday, May 3rd.

Explanation:

Plane left at 12pm and takes 17 hours.

Add 12 and 17:

= 12 + 17

= 29

There are 24 hours in a day. The number of hours into the next day is therefore:

= 29 - 24

= 5 hours

If the plan arrives 5 hours into the next day, that would mean that it arrived at 5am. Date of the next day is May 3rd, a Sunday.
